Funny! Was it published on April Fools' Day?

Sounds like it was written by a pre-pre-Alpha version of ChatGPT...
They certainly like to repeat that "1.5 times the power rating" BS...  :palm:

Then there's the next page about inductors!  ::)

Oh dear:  all my vacuum-tube electronics operates well above 3 V applied to resistors of various types.
(Back in the 1970s, when A-B carbon composition resistors were popular, it was normal to apply 300 or 500 V across high-resistance 2 W resistors.)
I went to the trouble of sending the company an e-mail demanding where they got the absurd article about resistor voltages.

you mean a version which knew zilch about Ohm I suppose :) ?

oh and then, I wonder about the destiny of all those poor resistors used in tube circuits

oh my golly !

:D

Even more ridiculous than their mis-information on resistor voltage ratings.

I like the statement: "AC or DC current can flow through an inductor, but not simultaneously." 

Makes me wonder how I ever managed to get any of my switching PSU designs to work.

Depends how you interpret "alternating" in AC.  If you mean the current direction reverses, then that statement is sort of correct.  If you interpret AC as meaning the non-DC component of a waveform its false.  But we abuse the notation horrendously all the time, since we talk of AC voltages...

Would it spoil our assessment of the company's competence if everybody contacted them to request such components?
There are lies, damned lies, statistics - and ADC/DAC specs.
Glider pilot's aphorism: "there is no substitute for span". Retort: "There is a substitute: skill+imagination. But you can buy span".

I think I'm going to go back to text books and encyclopedias for finding things out.

And from the "Difference Between Resistor and Capacitor" article:-

"Resistors are essentially switches that turn currents on or off."

"...adding resistors in series increases resistance, while adding capacitors in series increases capacitance."
